[GreenKeys] Northern radio TU type 174 model 1 and RTTYquestions

[jpoulton at email.unc.edu]

If one of you gents would send me a high-quality scan of the
174 manual (and any other Northern Radio manuals you might
have), or would be willing to lend me a manual briefly, I'll start a 
Norther Manual archive, parallel to the
TMC one.  It turns out there's actually some overlap,as TMC
made use of some Northern equipment in some of its systems.
